912 Birds of Celebes: Puffinidae. 



Distribution. From North Celebes to the Sandwich Islands: — Kema, North Celebes 

 (P. &F. Sarasin b l,b 2); Bonin Islands (Hoist. 5, 6]\ Krusenstern Id., N. Pacific 

 (H. J. Snow 1, 6); Sandwich Islands (Knudsen a 1, 2, V). 



A single specimen of a white-bellied Wedge-tailed Shearwater was obtained 

 by the cousins Sarasin at the N. E. extremity of Celebes in September, 1893, 

 and was identified by us with P. chlororhynchns Less., but now, after much 

 uncertainty, we hold it to be Mr. Salvin's P. cuneatus. Ordinarily Puffinus 

 chlororhynchus has the under surface sooty-brown and P. cuneatus white, and from 

 Mr. Salvin's measurements it appears that the middle and outer toes of the 

 former are equal in length, but in the latter the middle toe is given as about 

 3 mm the longer. A form of P. chlororhynchus has, however, been figured by 

 Gould (as immature) with a very pale grey under surface, while Salvin 

 describes one of the types of P. cuneatus as — compared with the other — 

 "greyer beneath, especially over the breast, flanks, and lower abdomen". We 

 hardly doubt that Salvin, the chief authority on the Petrels, is in the right 

 in separating the two forms, but we have no idea how such specimens as these 

 latter, which are not fully considered by him, may be distinguished from one 

 another. We at first held the Sarasins' specimens for the pale form of 

 P. chlororhynchus.
